RF & coaxial connectors uses. In RF (radio frequency) applications the cable is required to provide a consistent level of impedance at the point where the connection is made. This type of cable is provided with a shielding that serves to insulate the RF being carried through the cable from interference from outside the cable. Measurement of Dielectric Material Properties capacitive termination, while calibration in coaxial line measurements can be made using either short circuited, open circuited or matched load termination. The measurement method allows the measurement of permittivity and permeability of the dielectric material. Figure 1 – Measurement using TR method with a waveguide. Basic Antenna Theory - Wireless Dipole, Slot & INF antennas • Slot antenna: a slot is cut from a large (relative to the slot length) metal plate. • The center conductor of the feeding coaxial cable is connected to one side of the slot, and the outside conductor of the cable - to the other side of the slot. – The slot length is some (λ/2) for the slot antenna and
